From the very beginning (just few minutes after booking request) PK was very helpful and trying to help us with our trip. He let us check in much earlier than we supposed to. Helped us with our transfer from and to the airport. He suggested some places and all turned out to be very good ones.
About the apartment, I think it is much more than what is described. First of all apartment itself looks more beautiful than the pictures. Also its location is just perfect, just in front of the building is the metro and BTS station. I cannot recommend this place more.
